Application filed October 27, 1908. Serial No. 459,796.

To all whom it may concern:

Be it known that 1, Earn V. EsTILL, a citizen of the United States,residing at Roswell, in the county of Chaves and 'lerriv tory of NewMexico, have invented certain new and useful Improvements in Smoke andDust Arresters for Railways, of which the following is a specification.

This invention consists of novel improved means for use in connectionwith steam cars particularly for arresting smoke and dust. in so far asthe latter mentioned purpose of the invention is concernedv the same mayalso be employed in connection with electric railway trains to decreaseto a material extent the annoyance arising from dust and dirt drawnalong by the rapid progress of the care.

For a full understanding of the invention, reference is to be had to thefollowing detail description and the accompanying drawings, in which-Figure 1 is a side elevation showing a railway train having theinvention applied thereto; Fig. 2 is an enlarged front elevation of theforward passenger car of the train showing the mounting of the hopperthereon and connections with the air pipes; Fig. 3 is an enlarged topplan View of the parts of the invention supported by the front car andshowing the air pipes partly broken away; Fig. 4: is an enlarged detailview showing the connection of the draft pipe with the smoke stack ofthe engine; Fig. 5 is an enlarged detail view of the connections betweenthe sections of the air pipes; and Fig. 6 is an enlarged fragmentaryview bringing out more clearly the manner of connecting the air pipeswith the cars of the train so as to permit of drawing dust, dirt, orforeign matter into said pipes, Fig. 7 is an enlarged sectional view onthe line rom of Fig. 3 bringing out more clearly the form of thedischarge opening and valve located adjacent to the branches of the airpipe.

Throughout the following detail description and on the several figuresof the drawings similar parts are referred to by like referencecharacters.

Referring to the drawings particularly and describing the specificconstruction of those improvements embodying the present 1 invention,the numeral 1 indicates the cars of a railway train, the numeral 2 theengine, and the numeral 3 its tender.

In carrying out the invention it is contemplated to carry 0r convey thesmoke and products of combustion. passing from the chimney of the engine2 rearwardly there-- from and distribute the same upon the roadbed ofthe track over wiich the cars pass. The manner of distribution of thecinders, smoke, or other products of combustion is such as to arrestdust such as might be caused to arise from the road-bed as the rollingstock travels thereover.

As shown more clearly in Fig. l the engine 2 and its tender 3 support alongitw dinally arranged draft pipe 4, the front end of which is open asshown at 5 and at the same time formed with a downward extension 6adapted'to receive the upper end of the smoke-stack 7 of the engine 2.Suitable supporting standards 8 are employed to support the pipe 4: andthe rear end of said pipe extends downwardly as shown at 4* so as toenter a hopper 9 preferably carried by the front platform of the car 1just in rear of the tender 3. it will therefore be seen that as thetrain proceeds the smoke and products of combustion are carried by thedraft created through the pipe 1 to the rear end of said pipe and thenceprecipitated into the hopper 9. Adjacent to the hopper 9 is mounted anexhaust fan 10 and said fan is designed to force the smoke and otherproducts of combustion, received thereby at its central portion, to anair pipe 11, branches 12 of which extend lengthwise of the cars 1 andpreferably at opposite sides thereof. The pipes 12 branch from the pipe11 at a point a short distance below the hopper 9. Near the point wherethe pipes 12 branch apart the bottom of the pipe 11 is formed with adischarge opening normally closed by a valve 13 adapted to be operatedby handles 14 at opposite sides of said pipe 11. Should it be desired tohave access to the pipe 11 at the point of branching of the pipes 12therefrom, and for purposes of cleaning, repairing, or the like, thevalve 13 may be readily opened. At intervals in their length the branchpipes 12 are formed with downwardly projecting outlet pipes 15 fromwhich the cinders and products of combustion passing through the pipes12 are discharged downwardly upon the road-bed be neath the cars 1 asthe latter move forwardly. Necessarily the pipes 12 will be made insections carried by each of the cars l and such sections will be joinedtogether in any suitable way and preferably by making the rear ends 12"of the sections flexible so that the rear extremities of the pipesections on a front car may be received by the front extremities ofsimilar sections on .a rear car. A sort of male and female joint isprovided and the flexibility of the ends of the pipe sectionsaccommodates for ready turning of the cars as a train passes aroundcurves in the track.

The exhaust fan 1O is operated by means of a driving connection leadingfrom the adjacent axle 16 of the car 1. A sprocket wheel 17 on the shaftcarrying the fan is connected by a sprocket chain 18 with a similarsprocket wheel 19 on the axle 16 above referred to. While the train isin motion therefore the fan 10 is operated so as to produce a forceddraft through the pipes 12 whereby to convey the products of combustionalong said pipes to be discharged downwardly upon the road-bed, therebyarresting the dust and providing furthermore an excellent covering forsuch road-bed Also located at intervals in the length of the pipes 12are upwardly and forwardly inclined branch pipes 20 which extend throughthe floors of the cars 1. It is contemplated that these pipes 20 willform a means for removing dust, dirt, and other foreign matter from thecars. The draft produced in the pipes 12 will of course cause a suctiontending to remove dirt and dust in the manner above mentioned.

If desired special cleaning appliances such as may be operated byexhaust air may be connected with the branch pipes 20 so that the cars 1may be thoroughly cleaned whenever desired and convenient. The pipes 20also afford-to a certain extent a convenient means conducive to thoroughventilation of the cars l and in this connection it may be noted thatthe upper ends of the pipes 20 and including a draft pipe supported bythe 7 engine of the train and having its front end open, a hoppercarried by the platform of a car of the train and arranged so as toreceive therein the rear end of the draft pipe on the engine, a fanadjacent to said hopper and connected therewith, an air pipe leadingfrom said fan downwardly and rearwardly, branch pipes extending fromsaid air pipe longitudinally of the cars of the train and adjacent toopposite sides of the latter, downwardly extending discharge pipesconnected with said branch pipes at intervals, and means for driving.the fan aforesaid.

2. The combination with a train, of smoke and dust arresting means suchas described and including a draft pipe supported by the engine of thetrain and having its front end open, a hopper carried by the platform ofa car of the train and arranged so as to receive thereinthe rear end ofthe draft pipe on the engine, a fan adjacent to said hopper andconnected therewith, an air pipe leading from said fan downwardly andrear wardly, branch pipes extending from said air pipe longitudinally ofthe cars of the train and adjacent to opposite sides of the latter, theair pipe being formed with adischarge opening adjacent to the pointwhere the branch pipes extend therefrom, a valve normally closin saiddischarge opening,- handles at opposite sides of the air pipes foroperating said valve, and discharge pipes projecting downwardly from thebranch pipes aforesaid and located at intervals in the length thereof. tj In testimony whereof I afiix my signature in presence of twowitnesses. v L V I EMIT v.
